[Xen-devel] Possible regression with 3.13

We appear to have a regression in 32-bit 3.13 Linux dom0 --- sometimes (often) dom0 gets stuck somewhere in RCU while running an HVM guest (with "INFO: rcu_sched self-detected stall on CPU..." message being the first indication of things not going well).

I believe this was brought in by 39cf275 merge. I am trying to bisect this merge but having a bit of tool trouble. While I am doing this, if anyone noticed any issues with 32-bit dom0 recently, please let me know.

I see this most often with 4.1 but I think unstable is also affected.
